Tom,
You had mentioned earlier that:
Yes! Jquery is included with exported games, and it has some excellent AJAX wrappers. These will be available in C2 soon hopefully as they open the door on what can be achieved massively.
AJAX also will be able to manage some multiplayer online games as well (turn based and puzzle). HTML5 websockets will be able to handle real time multiplayer games.
When the AJAX plugins are completed I'll write some tutorials on how these can be applied easily. I'll also write some sample server side code in multiple languages to make it easy for people to install.
Do you still plan to write up a quick tutorial on how all of this is done? I plan on developing (don't laugh) an HTML5 rendition of Shadowgate that doesn't kill the user every three seconds. <img src="smileys/smiley2.gif" border="0" align="middle" /> I will need to have, of course, a login page and a way to manage which rooms, events, items etc each individual user has.
While the method of maintaining a database on the user's computer would be simple I'm guessing it wouldn't take much for them to hack the XML or text code in the file. Hence the need for sql database connectivity. I am decent with sql and okay with php, but have almost no knowledge of AJAX.
